Abstract (en)

[origin: WO2020060690A1] The present disclosure generally relates to processes to produce alpha-olefin oligomers and poly alpha-olefins. In an embodiment, the present disclosure provides a process to produce a poly alpha-olefin (PAO), the process including: introducing a C6-C32 alpha-olefin and a catalyst system comprising activator and a metallocene compound into a continuous stirred tank reactor or a continuous tubular reactor under reaction conditions, wherein the alpha-olefin is introduced to the reactor at a flow rate of about 100 g/hr or more; and obtaining a product comprising PAO dimer and optional higher oligomers of alpha-olefin, or a combination thereof, the PAO dimer comprising 96 mol% or more of vinylidene, based on total moles of vinylidene, disubstituted vinylene, and trisubstituted vinylene in the product. In at least one embodiment, a process includes functionalizing and/or hydrogenating a PAO product of the present disclosure. In at least one embodiment, a blend includes a PAO product of the present disclosure.
